My droplet is using “Ubuntu WordPress 4.9.1 on 16.04”

When I try to install the metric agent: (curl -sSL https://repos.insights.digitalocean.com/install.sh | sudo bash)

I am getting the following output

Cleaning up old sources…OK
Verifying machine compatibility…OK
Verifying compatibility with script…OK
Installing apt repository…
Preconfiguring packages …
dpkg: error processing package libc6:amd64 (–configure):
package libc6:amd64 is not ready for configuration
cannot configure (current status ‘half-installed’)
Errors were encountered while processing:
libc6:amd64
E: Sub-process /usr/bin/dpkg returned an error code (1)

How can I fixed?
